About ten years ago. I accidently raced a marked patrol car. I heard an engine rev when the light turned green and I took off. I did notice it was a patrol car when he turned on all the colored lights on his roof. [I was winning!].
Luckily he didn't let me get going too fast and he was cool. After a long conversation he only gave me a warning.
Then he asked if he could give me some advice.
"Next time you race someone, you might want to look over and see if they're driving a patrol car."
